IEC 63522-49:2025 This part of IEC 63522 is used for testing all kinds of electrical relays and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use. This document defines a standard test method for long term stability of sealing.

Scope 1.1 General 1.1.1 These requirements cover Distributed Energy Resource Systems (DER systems) that contain multiple DER units and associated control equipment that provide electrical energy to loads within the DER system. The DER system may utilize one or more DER units of any type. DER systems may also provide energy to the area EPS (Electric Power System) if present. This Standard…

Domaine d’application 1.1 Généralités 1.1.1 Ces exigences s’appliquent aux systèmes de ressources énergétiques distribuées (systèmes RED) qui contiennent plusieurs unités de RED et l’équipement de commande connexe qui fournissent de l’énergie électrique aux charges à l’intérieur du système RED. Le système RED peut utiliser une ou plusieurs unités RED de n’importe quel type. Les systèmes RED…

This specification defines a standard data format for referencing software artifacts that match the data model of modern distributed version control systems. This format includes the typical tree-like structure of a filesystem hierarchy, but also, special nodes to track revisions and releases, as well as the full status of a version control system, with all its development branches. A key…
